private fun getUserProxy(context: Context): Data {
    return try {
        val declaredField = WifiConfiguration::class.java.getDeclaredField("mIpConfiguration")
        declaredField.isAccessible = true

        val data =
            (context.applicationContext.getSystemService(Context.WIFI_SERVICE) as? WifiManager)
                ?.configuredNetworks
                ?.asSequence()
                ?.mapNotNull {
                    try {
                        declaredField.get(it)
                    } catch (e: Exception) {
                        e.printStackTrace()
                        null
                    }
                }
                ?.mapNotNull {
                    try {
                        (it.javaClass.getDeclaredField("httpProxy").get(it) as? ProxyInfo)
                    } catch (e: Exception) {
                        e.printStackTrace()
                        null
                    }
                }
                ?.find { !it.host.isNullOrEmpty() }
                ?.let { Data(it.host ?: "", it.port.toString()) }
                ?: Data()

        declaredField.isAccessible = false
        return data
    } catch (e: Exception) {
        e.printStackTrace()
        Data()
    }
}

data class Data(
    val host: String = "",
    val port: String = ""
)
